Description

The TMUX8108 and TMUX8109 are modern high voltage capable analog multiplexers in 8:1 (single ended) and 4:1 (differential) configurations. The devices work well with dual supplies, a single supply, or asymmetric supplies up to a maximum supply voltage of 100 V. The TMUX8108 and TMUX8109 support bidirectional analog and digital signals on the source (Sx) and drain (D) pins.

All logic inputs support logic levels of 1.8 V, 3.3 V, 5 V and can be connected as high as 48 V. Fail-safe logic circuitry allows voltages on the logic pins to be applied before the supply pin, protecting the device from potential damage.

The device family provides latch-up immunity, preventing undesirable high current events between parasitic structures within the device. A latch-up condition typically continues until the power supply rails are turned off and can lead to device failure. The latch-up immunity feature allows this family of multiplexers to be used in harsh environments.
